Notes:
It'd be hard to find a single comic responsible for the creation of more superheroes than "More Fun Comics". Many were forgotten, but a few (Dr. Fate, the Spectre, the Green Arrow, Speedy, Johnny Quick, Aquaman, and Superboy) have certainly outlived their original home.

Note: Began publication as New Fun Comics until the name changed to its more familiar title at issue #7.
Dr. Fate's first appearance was in More Fun Comics #55 but he did not make his first cover appearance until More Fun Comics #56
